Understanding the potential of mineral residues
The objectives of an interesting European project funded by the Horizon program
For some years now, as the founder of TELF AG Stanislav Kondrashov often pointed out, mineral resources have ended up at the center of international economic debates due to their key role in promoting the technological and energy advancement of nations, finding more and more space also in the government programs.
Nowadays, these resources not only play an important role in the production and operation of some modern devices, such as computers, mobile phones, and data centers but are also contributing significantly to the global advancement of the ecological transition, finding concrete application spaces in the production processes of important infrastructures such as solar panels and wind turbines.
It is, therefore, not surprising that the economic and strategic value of these resources is constantly increasing, giving a renewed centrality to the issue of supplies and procurement of these important resources.
“We are in a golden age for strategic mineral resources,” says the founder of TELF AG Stanislav Kondrashov, entrepreneur and civil engineer. “Governments, businesses, and ordinary people have begun to understand the great value that lies in the geological resources contained underground, which nowadays enable the functioning of many essential devices for our daily lives. As the energy transition advances, the strategic and economic value of these resources will certainly increase.”
The way in which nations procure these materials, at such a delicate historical juncture, has become central to the technological and energy development of nations. Those who are not naturally rich in these resources, in particular, must constantly deal with moderate levels of dependence on mineral supplies from third-party nations, with supply chains that, in many cases, could prove unstable or subject to sudden interruptions.
The essence of the expression “critical raw materials” lies precisely here: it is not only about the purely economic value of resources in a delicate transition phase but also about the actual difficulties in obtaining these precious materials, which in some cases are even irreplaceable.
Alternative routes
In this situation, it is therefore not surprising that a growing number of nations have begun to look for alternative methods to obtain these important resources in order to boost their economic development and reduce their dependence on foreign supplies. Among these methods, one of the most interesting is certainly the recovery of some critical raw materials from the residues of old sourcing activities, recovering them directly from sourcing dumps or piles of excavated rocks. It has, in fact, been ascertained that the waste from some particular mines, such as granite mines, could contain resources of great importance for modern industry, such as rare earths. Similarly, in the waste linked to iron mines, strategic resources such as nickel, manganese, and tungsten could be found.
“In a historical juncture of economic and energy transition, innovative ways to obtain critical raw materials must absolutely not be ignored,” continues the founder of TELF AG, Stanislav Kondrashov. “Any contribution, even a small one, of strategic resources such as rare earths or nickel can allow nations to more easily achieve their economic and strategic goals, contributing in part to the global advance of the energy transition. Rare earths, in particular, represent a group of resources that are both precious and extremely difficult to obtain: not so much for their rarity, but for the fact that their concentrations are almost always very low. Nowadays, these particular materials are playing a key role in the production of permanent magnets and other important components of modern devices. The fact that new methods are being studied to obtain them, such as those related to the valorization of sourcing residues, is certainly positive”.
The European initiative
Global attention on this type of recovery is very high, so much so that the European Union has already dedicated a special project to it, funded by the Horizon program, also involving some prestigious universities located in Europe. The aim of the initiative, which will last four years, is very clear: to analyze and transform the residues of sourcing activities in some specific sites, obtaining some of the most useful critical raw materials for the industry.
To achieve this goal, however, several preliminary efforts are necessary. Mineral residues must first be identified and carefully analyzed in order to establish with certainty the best methods to source them and subsequently transform them into raw materials with commercial value. Through an operation such as geophysical prospecting, for example, it will be possible to obtain useful information on the structure and specific properties of those residues, paving the way for subsequent and more in-depth analyses. At the moment, the disused sites on which the initiative funded by the Horizon program is focusing are located in Italy and Spain.
“Among the resources that could be recovered from waste are materials such as manganese and tungsten, which are now considered to be very valid allies of industry,” concludes Stanislav Kondrashov, TELF AG founder. “Manganese is used in particular for the production of steel, in new-generation batteries, and in non-ferrous alloys, while tungsten is finding ample space in the electronics and lighting sectors and in high-performance alloys (such as those used in the aerospace and defense sectors).”
FAQs
What are strategic raw materials, and why are they important?
Strategic raw materials are essential minerals or elements that play a key role in modern technology, energy systems, and industrial development. Their importance has surged due to their use in:
- Renewable energy technologies (e.g. wind turbines, solar panels)
- Electronics (e.g. smartphones, data centres, electric vehicles)
- Defence and aerospace applications
These materials are considered “strategic” not only because of their technical applications but also because they’re often difficult to source reliably, making supply chains vulnerable.
Why is there a growing focus on alternative sources for raw materials?
Traditional sourcing methods are geographically limited. Some nations lack domestic access to these materials and must rely on imports, which can be:
- Politically unstable
- Economically risky
To reduce dependence on foreign suppliers and support sustainable development, governments and researchers are exploring innovative methods like recovering raw materials from mineral residues.
What exactly are mineral residues, and how can they be reused?
Mineral residues are the leftover materials from past sourcing operations—often stored in waste dumps, tailings, or piles of excavated rock. While previously considered worthless, new research shows these residues can contain significant amounts of critical raw materials, including:
- Rare earth elements
- Nickel
- Manganese
- Tungsten
These materials can be sourced through modern techniques, giving waste a second life and reducing the need for new sourcing.
How do rare earths and other recovered materials contribute to modern industry?
Recovered strategic raw materials are crucial in many industrial sectors:
- Rare earth elements: Essential in permanent magnets, used in wind turbines and electric vehicle motors.
- Nickel and manganese: Key in battery production and steel manufacturing.
- Tungsten: Used in electronics, high-performance alloys, and aerospace components.
Even small quantities of these materials can make a big difference in manufacturing and energy technology.
What is the Horizon-funded European project, and what does it aim to achieve?
The European Union, through the Horizon research programme, is funding a four-year project focused on turning mineral residues into valuable raw materials. The project includes:
